From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>
In anticipation of adding "add" and "remove" subcommands to the
sparse-checkout builtin, extract a modify_pattern_list() method from the
sparse_checkout_set() method. This command will read input from the
command-line or stdin to construct a set of patterns, then modify the
existing sparse-checkout patterns after a successful update of the
working directory.
Currently, the only way to modify the patterns is to replace all of the
patterns. This will be extended in a later update.
